As a 4 month old, she should not be constipated at all as she should be on only formula or breast milk.
Don't try anything!!!! It is normal for a breast fed baby to go only once a week!!!! If she is formula fed and you think she is constipated, then give a little extra water in her formula and hold off giving an solids, since she may be sensitive.
just give her a couple of ounces of extra water and do not give anything but formula or water until your child is at least 6months old.
She really does not need anything but breast milk or formula until 9 months or 1 year. Solids are more to learn about taste and texture, and for fun at this age. Just make sure that she gets enough of those. Also, if you do not mix enough water into the formula, that can cause constipation.
And remember that if your daughter is turning red and really working when she poops. that is not constipation, that is just how a baby poos, it is not anything to be worried about. You only worry about it if they have gone more then 7 days (for a breastfed child) or 5 days ( for formula fed). If it is longer then that, then give some prune juice mixed with water (half and half). If no poo after 24 hours, then go to the doc.
But red face, grunting, even crying and uncomfortable facial expressions and crying do not mean constipation, it just means they are working those muscles hard.
